目的掌握2011年《食用盐碘含量》标准实施后上海地区孕妇和学龄儿童的碘营养状况。方法按人口比例概率抽样法抽取30个街道(镇),每个街道(镇)中随机抽取1所小学,每所小学中随机抽取50名8~10岁学生,测量其甲状腺容积和尿碘含量,并检测其家中食用盐碘含量。在每个抽取的街道(镇),抽样检测20名孕妇的尿碘含量。结果 8~10岁学龄儿童甲状腺肿大率为0.9%。8~10岁学龄儿童、孕妇的尿碘中位数分别为171.40、126.53μg/L。8~10岁学龄儿童家中合格碘盐食用率为72.52%,碘含量中位数为24.8 mg/kg。结论上海市儿童甲状腺肿大率低于国家标准,儿童碘营养水平适宜,孕妇碘营养不足。食盐中碘的含量需提高至最优水平。要加强孕妇碘营养健康教育。
Objective To understand the iodine nutrition status of pregnant women and school-age children in Shanghai after the implementation of the “Edible Salt Iodine” standard in 2011. Methods A total of 30 streets (towns) were sampled according to the Probability of Population Proportion sampling. One primary school was randomly selected from each street (town). Fifty students aged 8 to 10 were randomly selected from each primary school to measure the thyroid volume and urinary iodine , And detect the consumption of salt iodine in their home. Urine iodine was tested on 20 pregnant women in each of the extracted streets (towns). Results The prevalence of goiter in children aged 8-10 years was 0.9%. The median urinary iodine of pregnant women aged from 8 to 10 were 171.40 and 126.53μg / L, respectively. The prevalence of qualified iodized salt was 72.52% in the school-age children aged 8-10 years, and the median iodine content was 24.8 mg / kg. Conclusions The goiter rate of children in Shanghai is lower than the national standard, the iodine nutrition level of children is suitable, and the iodine nutrition of pregnant women is insufficient. Salt iodine content needs to be raised to the optimal level. To strengthen iodine nutrition health education for pregnant women.
